Obtaining insights on the illicit consumption of endangered wildlife products is challenging, especially when the study objects are the super-rich. This research note draws upon my experience interviewing nearly 1,000 rhino horn consumers in Vietnam. Trust is crucial in such interactions. No interviews could have been conducted without good rapport between interviewers and respondents. Nonetheless, soliciting interviews requires skills that one cannot expect to teach enumerators in the short term. This includes a winning sense of humour, colourful life experience, and true grit. Once good rapport is established, the use of specialised questionning techniques or bias-mitigation tools becomes unnecessary. Instead I suggest a practical approach to study consumers of illegal and luxury wildlife products in an Asian context.
